Actually a 2000 with next to no miles is about right for the full assembly. The 2000 will require the most work though as it doesn't have the WP in the right place, plus you'd have to run the 2.5 heads with the 2.5 intakes or adapt the cables and such to run the 3L heads with the 3L intakes since the heads are oval ports and won't adapt well to the 2.5 intakes without an adapter plate.
